    Just wondering where are you ever going to come across an uninstalled capacitor like your that needs to be discharged. That thing seems puny as if it were micro amps. I'm no safety officer or electrician, but why would you have to go through all that trouble for a little capacitor. Seems like a waste of time.

    Light, heat, sound… screwdriver fits the bill

    @pixuma ya just jam it into the table edge also, looks like a metal edge.

    @SlayanicDoom if you are salvaging something or just trying an experiment for fun and a device or board has a huge capacitor, (like one in a CRT monitor case) those things can be very dangerous. Computer geeks and tinker bugs like me come across this situation plenty of times.

    im an engineer, and this is a very foolish way to discharge a capacitor. a cap that is that small and less than 50 volts can easily discharged with a screwdriver or just short the terminals. for a high voltage capacitor doing something like that can be dangerous, depending the size of the cap and the voltage its charged to. any capacitor that could be considered dangerous (like 50+ volts) should be discharged through a resistor of a appropriate resistance and power rating.

    i like my 400wv 220mF capacitor, it sparks huge 🙂

    why do u need to put capacitors??

    if its safe to handle now how did he handle it in the first place?

    lol 100s of microFarads might not even light the bulb for a sec, u dont need a motor or anything else
